There's something to be said for having a first aid kit at the ready wherever you go. I used to slip a few bandages in my wallet just in case, but this Altoids tin first aid kit has enough bandages inside to patch up the cuts and bruises you might get during your average day (and then some!)

Instructables user Ekzile put together this kit, and stocked it with a handful of small and medium sized adhesive bandages, folded up medium and large gauze pads, a small knife with a fingernail file on the side, plenty of sterile alcohol pads, some waterproof tape, and a vacuum-sealed bag with cotton swabs and cotton balls inside. He then wrapped the whole thing up with a shoestring, and slipped the end product in his pocket.

Granted, if you carry a bag or backpack with you everywhere, you could use a bigger container and carry more in your kit. If you drive from place to place, you'd probably be better served with an emergency car kit. Still, we could see swapping out the shoestring for some paracord, and maybe work in a tube of antibacterial ointment in the tin as well. How would you improve on the kit?
